I drove my dually year around until I bd'd it and still would but don't need to so I don't. I used to tow a 24' enclosed car hauler with 5 sleds in it across the U.P. when I probably shouldn't of but never had problems. I drove on I75 one time when they had pulled the county trucks off the road because of how hard it was snowing. I was pulling that trailer and had snow coming over my hood. I didn't have any problems, I just didn't stop. I started as rain then turned to wet heavy snow then had fluff on top. I had good snows on her and weight in the back as well.
